Moreover, the MFT 1721 is one of a handful of installation testers capable of testing specialist type B RCDs commonly found protecting temporary generator supplies and other DC installations. The MFT1721 can store a Z-ref value (Ze measurement), calculating and displaying an R1+R2 reading after conducting a Zs test. Although, this feature should be reserved for confirming that a previously recorded R1+R2 continuity value is indeed correct, having energised the circuit for live testing.\u003c\/p\u003e\n\u003cp\u003eTwo rotary dials provide a user-friendly means of operating the instrument, with primary and secondary test settings being colour coded, reducing the chance of selecting an incorrect function or range. Test results are displayed on a large, dual format, crystal clear display that can be viewed from even the most acute of angles.\u003c\/p\u003e\n\u003cp\u003eDesigned for ease of use in the harshest environments, the instruments within the \u003ca href=\"https:\/\/alertelectrical.com\/brands\/megger\"\u003eMegger MFT Multifunction Tester\u003c\/a\u003e range are encased in hard-wearing rubber, improving grip and providing additional shock protection in the event of impact.
